Eu tenho um ponto de acesso sem fio no meu telefone que acabei de configurar. O telefone é um Samsung Galaxy S2 fornecido pela ATT Wireless.
Quando o configurei pela primeira vez, o Network Manager reconheceu o ponto de acesso e consegui me conectar.
Então, um ou dois dias depois, a conexão só permanecerá por cerca de um minuto.
Consultei os links a seguir e nenhuma das sugestões teve impacto na minha situação:

Não é possível conectar VPN pptp em 13.10
(Isso é uma VPN)
Problema de conexão Wi-Fi
(configurar o sudo iw wlan0 set power_save off não teve efeito)
Eu posso manter uma conexão com outros roteadores wifi, trabalho em casa etc. Apenas não o telefone.
Estou executando o seguinte sistema:
Linux 3.11.0-19-generic #33-Ubuntu SMP
Description: Ubuntu 13.10
Release: 13.10
Codename: saucy
O driver (conforme fornecido pelo lspci) é:
Network controller: Intel Corporation Wireless 3160 (rev 83)
Quando perco a conexão, o dispositivo não é mais visto pela verificação do SSID. Eu tenho que reiniciar wpa_supplicant para vê-lo novamente e se conectar a ele.
Tailing / var / log / syslog oferece alguns trechos do que está acontecendo:
A conexão inicial bem-sucedida:

Para "bssid CTRL-EVENTS-DISCONNECTED = 20: 64: 32: 3a: 91: 85 reason = 4", não consigo encontrar um recurso que explique que razão = 4 significa.
Vimos que na tentativa subsequente, o link expira com um bssid = 00: 00: 00: 00: 00: 00 reason = 3
com o valor CTRL-EVENT-DISCONNECTED
O que faz sentido, pois o wpa_supplicant não consegue mais encontrar o dispositivo.
Posso repetir este processo executando:
ps -ef | grep wpa
kill -9 (the pid of wpa_supplicant)
Adicionar log detalhado ao wpa_supplicant mostra o seguinte:

Qualquer que seja o EAPOL, ele não está mais sendo autenticado.
Então, como uma rápida recapitulação:
- Não é possível conectar-se à mobilidade sem fio (Samsung Galaxy S2 via ATT) por mais de 1 a 5 minutos
- Pode se conectar a outros pontos de acesso sem fio sem problemas.
- Os registros indicam que o dispositivo não pode ser autenticado e atinge o tempo limite.
Outras postagens do fórum indicam um problema no kernel ou em um driver de dispositivo. Minha situação é confusa, pois posso me conectar a pontos de acesso Wi-Fi.
Ah, e não tenho certeza se é o telefone ou não. Ainda não testei em outros dispositivos. Meus instintos estão me dizendo que não é o telefone.
Obrigado por dedicar um tempo para me ajudar com isso. Apenas migrei do Debian Wheezy para o Ubuntu, então. . . isso é inútil, mas esse é o meu primeiro post no Ask Ask.
ATUALIZAÇÃO:
Eu removi o MAC ADDRESS desta máquina do telefone e simplesmente simplesmente autentico com o WPA2. Isso, obviamente, não fez nada.
Os registros parecem indicar que o dispositivo não honra mais a autenticidade da conexão. Na tentativa de isolar o wpa_supplicant, eu chamei o wpa_supplicant do terminal, passando o driver, e o ssid, mas isso muck com o NetworkManager que está rodando sua própria versão do wpa_supplicant e, aparentemente, eles não tocam bem.
O outro culpado pode ser dnsmasq, já que parece que está consultando meu telefone para uma entrada dns e talvez esses dois não estejam interagindo muito bem "Eu gostaria de uma entrada dns. Claro. Eu gostaria de uma entrada dns novamente. Espere um segundo, eu acabei de te dar dois minutos atrás. "
Colisão diária: você não adora quando problemas bem formados fornecem histórico e registros, bem como históricos e log, passam despercebidos? Portanto, a conexão é estável e contínua quando conectada. Algo está com o sinal então. Talvez seja um mau motorista? Não tenho certeza, já que essa questão é bastante inadequada.
